There are two paths:
1. hardcoded driver (not going to be upstreamed, but works today with libcamera)
- sdm845-next git tree[1] (imx519 camera for sdm845-oneplus-common.dtsi)
2. mipi-ccs driver (tested locally with imx519 on D-PHY, but doesn't with C-PHY
yet or we haven't found right frequency which mipi-ccs would agree on)
a. needs C-PHY div/multiplier fix (I assume)
b. needs metadata patches until [2] get merged
c. needs initial sequence to be uploaded and packaged for distros
d. needs libcamera integration
